Schifer weight 1m2 during disassembly

The weight of slate tiles, also known as "Schifer," is an important consideration when analyzing roof materials. This weight is essential for the processes of installation and disassembly. The weight of each square meter of Schifer tiles varies, which affects handling safety and convenience during roof replacement or maintenance.

Schifer tiles are widely used in roofing because of their inherent qualities and long lifespan. They are renowned for their strength and beauty. Their weight, though, can make disassembly difficult. When doing repairs or renovations, roofers need to be very aware of the weight per square meter and plan accordingly.

Knowing the precise weight of Schifer per square meter is crucial for safety precautions and logistical planning for both homeowners and roofers. By ensuring that suitable handling methods and support structures are in place, this knowledge helps to prevent mishaps and damage during the removal and replacement process.

People can make well-informed decisions about roof maintenance and renovations by being aware of the weight implications associated with Schifer tiles. The efficiency and safety of roofing projects are greatly enhanced by this understanding, which is essential for determining load-bearing capacities and organizing transportation logistics.

Material Type Weight per square meter during disassembly
Slate Approximately 25-40 kg
Clay Tiles Approximately 40-60 kg

Why do you need to dismantle old slate

You should consider the advantages and disadvantages before deciding to remove the old slate roof. The roof replacement is, in fact, a fairly costly construction project. Unexpected issues could arise during implementation, raising the estimated cost of repairs even more. When should the old slate be taken apart?

    Critical physical wear. Outwardly, the sheets of slate have no significant damage and look quite normal, but due to natural aging, the strength of the slate is significantly reduced, it becomes very fragile, in some cases the sheets are easily broken off with their hands. Such a coating can receive significant damage at any time during heavy rain. As a result – water enters not only the attic, but also in living rooms. We will have to repair the decoration of ceilings and walls of the interior, and this much increases the cost of repair. Conclusion – do not expect the emergence of big problems, it is much more profitable to replace the old slate in a timely manner.

Slate becomes less dense with time and becomes more susceptible to damage, even from minor impacts.

The roof needs to be replaced if there are slate cracks.

The moss-covered roof gives the entire building an ugly, shoddy appearance.

The old coating may be reused or may need to be taken to a landfill in order to get rid of construction waste, depending on the state of the slate and the credentials of the masters. You should have an approximate idea of the total weight for transportation; this figure is calculated by factoring in the mass of each square meter of slate during disassembly.

Prices for various types of slate


"Knowing the weight per square meter of Schifer tiles is essential for safe and effective removal when disassembling the roof. Schifer tiles differ in weight based on their composition and thickness, which affects the logistics and safety precautions needed when disassembling them. This article discusses the variables that affect the weight of Schifer tiles, provides helpful advice on managing and figuring out weight distribution, and places a strong emphasis on safety precautions to guarantee a seamless disassembly without sacrificing structural integrity."

How to determine the weight of the slate of 1 m2 when disassembling

The specific type and technology used in the material’s production determine the technical specifications of slate sheets. There are two distinct types of asbestos-cement slate based on the sheet’s geometric shape.

Wave slate

Rectangular in shape, it is used as a facing and roofing material. Wave count varies from five to eight, as does their thickness and height.

The wave slate’s primary specifications

Installing the wave slate requires a slope of at least 12 degrees. The material is formed on automated lines from a specific mass, and the number of waves can vary based on the properties of the press forms. You can reduce the thickness of the slate without sacrificing the original technical data because the bending strength parameters increase with the number of waves. There are asbestos-cement slate sheets in waves 5, 6, 7, and 8. Nowadays, the majority of companies produce eight-wave slate instead of the five- and six-wave varieties, and Semillevova is hard to come by.

Technical characteristics of standard slate brands

Regulations for labeling the slate dictate that inscriptions must be applied to the extreme wave from the front side. For instance, a sheet with the marking 1750 × 1130 × 5.2 mm, 40/150 has dimensions of 1750 mm in length, 1130 mm in width, and 5.2 mm in thickness. There is a 40 mm wave height and a 150 mm gap between crests.

On one side of the sheet, marking is applied to the extreme wave.

Table: Weight of coating based on slate type.

Shifer brand Standard mass of one sheet Square meter weight
7 wave 1750 × 1130 × 5.2 mm, 40/150 ordinary (VO) 18.5 kg ≈9.5 kg
7 wave 1750 × 1130 × 5.8 mm, 40/150 reinforced (WU) 23 kg ≈11.8 kg
8 wave 1750 × 1130 × 5.8 mm, 40/150 ordinary (VE) 26 kg ≈13.3 kg
8 wave 1750 × 1130 × 6.0 mm, 54/200, unified (UV) 30 kg ≈15.1 kg
8 wave 1750 × 1130 × 7.5 mm, 54/200, reinforced (WU) 35 kg ≈17.9 kg

The wave slate’s physico-mechanical characteristics

The mass of asbestos -cement slate coating is the largest of all used roofing materials. A load of up to 18 tons may affect the roof with a total area of ​​100 m2, this is the weight of the most durable and thick slate. But do not be afraid of such additional efforts, it must be understood that during the calculation of the rafter system, snow and wind loads are taken into account, and they can be several hundred kilograms per square meter. Taking into account the cost of the verse of the rafter system, which is required by architects of the strength of the strength of the rafter system (1.4 coefficient), the additional maximum weight of the thick chipher of 18 kg/m2 does not have any noticeable effect on the strength and stability of the structure.

The roof’s rafter system was initially intended to support large loads.

Vital. Many contemporary businesses create their own technical specifications rather than using national standards when manufacturing their products. Remember this the next time you disassemble old coatings and figure out how much a square meter of slate weighs.

The slate’s dimensions are 1200 mm in length, 680 mm in width, and 5 mm in thickness if the structure is covered in sheets from the previous sample. Compared to modern sheets, this one is substantially smaller—its mass is only 8.6 kg. Old and new sheets cannot be combined, and materials cannot be docked due to the wave’s varying steps and heights. It is preferable to dispose of these coatings at the construction site landfill as soon as possible.

Flat slate

The goal is to produce personal plot fences. The sheets are heavy and have linear dimensions, with a thickness of up to one centimeter. Flat slate cannot be used for roofing because its technical specifications do not allow for its use as a roofing material. Moreover, it is not often used for barriers these days. Excessive weight makes installation more difficult, and inadequate physical strength indicators cut down on operating time considerably. For the construction of barriers around different land plots, buildings, and industrial facilities, there are now more affordable, sturdy, and dependable materials available.

There is no usage of flat asbestos-cement slate roofing.

Practical tips for the dismantling of slate

It takes skill and attention to dismantle the old slate, and safety regulations must be followed. Not only must the work be done at heights, but all of the designs have already lost their initial strength indicators, which raises the possibility of emergencies occasionally.

Vital. There should always be a designated roof staircase used. Make it short, and the work becomes safe and the old roof’s dismantling process is sped up considerably.

Safety precautions when removing the slate

Three regular nails that are at least 100 mm long, a piece of rope about two meters long, the attachment (whose dimensions should allow the upper part to rest on the slope), and the main rope for the slate’s descent onto the ground are all you’ll need to remove the slate.

Step 1: Get the nails ready. They need to be bent into the shape of the Latin letter Z, with one end at an angle of 180 degrees and the other at about 140 degrees. This type of nail will secure the rope in a dependable and timely manner, hastening the disassembly process and ensuring safety. Old sheets can also be used to install roofs over other home additions that don’t need new roofing materials because they are preserved.

Nails can be bent into hook shapes.

Step 2: Close the ladder or fasten wooden planks or rails to it. The step of the waves should match the distance between them. Since a step in most sheets is 200 mm, there needs to be 60 cm between each runner.

There are more runners screwed to the stairs.

Vital. A portion of the component should be exposed at the height of the slate by the stair legs. This parameter is four centimeters in our situation.

All materials maintain their original indicators because of the runners, which entirely exclude the drop of slate sheets on one side. Furthermore, working below reduces the risk of a slate falling on one’s head, making it much safer.

Step 3: Create a second staircase of the same size to be placed atop the incline. While the house’s slate roof is being disassembled, the second staircase is moved and temporarily fastened to the crate. You must devise any temporary locks or latches if there is any concern that the connection between the two stairs is unstable. They will guarantee the elements’ stable position regardless of the lateral loads that are actually acting.

Attached to the roof slope is an additional staircase.

Step 4: Create a piece of rope, referred to as the "spider," and two bent nails. This is a unique mechanism that lowers to the ground to support slate sheets behind the lower edge. This is how hooks are made.

  1. Tie a piece of rope with a length of about two meters long to the main long. Tie in the middle, two hanging segments should have the same sizes. Otherwise, the sheet will be pumped, and such a position may cause a wave of a wave from the lane.
  2. Tie bent nails to the ropes. Fix those ends of the nails that are bent at an angle of 180 °. In order to prevent them from falling out, it is recommended to bend the end of the nails as much as possible and in this way to reliably squeeze the rope.

The sheet is now securely held upright by the second (lower) nail hooks, which are placed on the slate’s edge.

The sheet is consistently held upright by the rope and nail hooks.

Step 5: Unfasten the sheet by pulling off the slate nails, then place it on the stairs and secure the ropes. One person should take a position behind the skate, grasp the rope with both hands, and then slowly release it. The sheet descends the runner gradually.

A rope secures the sheet, which is then carefully lowered.

Step 6: A second assistant gathers the slate sheets and stacks them. Sorting is done concurrently: whole are folded in one spot, cut in another, and cracked and rendered entirely useless are taken off in a pile with construction waste. With the use of this technology, you can remove all of the slate sheets from the house in a single work shift.

A stack of the roof’s removed sheets is placed on the ground.

Sensible guidance. It is advised to break the sheet on the roof and discard it right away rather than lowering it to the ground if it has a significant crack in it.

The truth is that it is extremely dangerous and is likely to crack during the descent. The assistant holding at the top may fall from the roof due to an unexpected loss of load, and pan fragments may hurt the worker at the bottom.

Roof analysis without sheet preservation

Comprehending the pragmatic implications is essential when addressing the weight of schist during disassembly. The weight of schist, a sturdy and frequently heavy material used in roofing, varies according to its thickness and makeup. Generally speaking, schist can weigh anywhere from 25 to 40 kg per square meter. Because of its weight, removal may present logistical challenges that call for careful planning and the right tools to ensure safe handling.

A thorough examination of elements like the schist’s state and the roof’s underlying structure is necessary during the disassembly process. Due to layers of accumulated moisture and dirt, older roofs may have heavier schist, which would increase the total weight per square meter. Employing scaffolding and lifting equipment appropriately are crucial for preventing damage to the roof structure and guaranteeing worker safety.

Furthermore, the logistics of disposal and transportation are impacted by the weight of schist. Heavy-duty vehicles are needed to transport removed schist, and disposal locations need to be able to handle the material’s weight and volume. Schist recycling options can also be investigated in order to lower disposal costs and minimize environmental impact.
